He doesn't explicitly say that is something he is programming for the long term. In fact, he mentions he is going into game coding full time, which makes it highly unlikely that you'll ever see this CVIII-HD remake.
The resolution is a little curious though, as it is in no way a standard resolution for any game platform. Though, admittedly, Japanese PC developers pull random resolutions right out of their ass all the time. I've seen odd number resolutions before. Truly wtf.
